[oi-dev] diagnose touchpad

[Stephan Althaus]

Hello!

I am looking for hints to diagnose the builtin touchpad.

It should work on the device node  /dev/kdmouse  and the old PS/2 driver 
mouse8042

On an older laptop (HP Elitebook 2530p) with OI 2021.10 booted from usb,
the following dtrace script shows "fbt::mouse8042_intr" events:

fbt::mouse8042_intr:return,
fbt::mouse8042_process_msg:return
{
     printf("%s returned %d \n", probefunc, arg1);
}

on the newer laptop (Dell Precision 7720) there are no events..


What can i do to dig deeper ?


Any hints are welcome!

Stephan
